Comparison of DOE’s SNOPR TV Test Procedure with CEA-2037-A 

This document compares DOE’s proposed test procedure from the Supplemental Notice of Proposed Rulemaking (SNOPR) for 

Television Sets (TVs), (78 FR 15807, March 12, 2013), to the Consumer Electronics Association’s (CEA) draft CEA-2037-A WD3.5 test 

procedure, “Determination of Television Set Power Consumption,” updated on October 11, 2012. 

This comparison highlights only the differences between the two documents. The first column shows the regulatory text from the 

SNOPR, while the second column contains a citation from the relevant section in the CEA test procedure for comparison. An empty 

cell denotes a topic not covered by the test procedure, while a cell with red text highlights any difference in language between in the 

SNOPR and CEA. 

Note that the page number references are to the page numbers of the pre-publication version of the SNOPR. 

 In this document, the proposed regulatory text begins on page 81. The discussion section of the SNOPR, page 15 to 68 of this 

document, provides a detailed explanation of DOE’s new proposal. It should also be noted that the formatting of the pre-publication 

NOPR is the only difference between this version and the version published in the Federal Register. The text is the same.

other devices on the network but will not allow access to a 

WAN. If the TV has multiple network connections, the TV 

shall be configured and connected to a single network

calculated using on mode and standby mode power 

consumption values as calculated pursuant to section 5.4.

kilowatt-hours per year, according to the following:

AEC = 365 * (Pon * Hon + PStandby-Active, Low * HStandby-Active, Low + 

PStandby-Passive * HStandby-Passive + Poff * Hoff)/1000

Where:

Pm = power measured in a given mode m (in Watts)

Hm = hours per day spent in mode m 

365 = conversion factor from daily to yearly

1000 = conversion factor from watts to kilowatts

-If TV is network capable, Hon = 5, HStandby-Active, Low = 19, and 

other H variables are zero.
